First Sentence stick pick:

My mother was doing that thing she did.  That thing with the rag in the sink.

She was OCD about the drain and would wipe it down six times after every use of the kitchen sink.  Not three times, nor five times, always six times.  She used the same rag each time too.  The rag was nasty and full of holes but she wouldn’t replace it with another one.

“Put the rag down, it’s time to go.”

Drew a Non Sequitur stick:

The plane was two hours late.

No wonder she was more off her rocker today than usual.  She hated flying.  Waiting made it worse.

Chose a last straw stick:

The last time they saw a movie.

It was the same darned movie they were showing in flight.  She didn’t like it back then and had made loud, snide remarks during it.  Maybe finding her book in the carry-on would be better.
